Description

This USB to Serial Adapter has been tested and works properly with all versions of TunerStudio.  We highly recommend this adapter is used if your tuning PC/laptop doesn’t have a DB9 Serial connector.  Or you can use another adapter with a genuine FTDI chipset (which this uses).

This adapter includes a 2′ extension cable, but we only recommend using the extension cable if you have vibration issues with the adapter plugged directly into your laptop. USB cable runs are more susceptible to noise than RS232, so we recommend using our standard 6′ tuning cable in combination with this adapter.

Product SKU: USB-2920 ( USB2920 )

Am I required to use this particular adapter for connecting to MegaSquirt?

  • It is not the only adapter that can work, but our tech department is very familiar with this adapter and it is the only adapter we can provide full technical and warranty support for. With this adapter, you can talk to a support team who both knows the USB adapter and knows MegaSquirt fully.

When should I use the USB extension cable included with this unit?

  • The cable is useful if you are dealing with a high vibration environment. However, it also picks up large amounts of electrical noise. If you are using the USB extension cable and experience problems where the ECU goes offline once you start the engine, remove the extension cable and plug the adapter directly into the USB extension port, and use the DB9 straight through cable to connect the adapter to the ECU.

Why would I get less noise with the DB9 extension than with the USB extension?

  • The RS232 side of the system uses a +12 to -12 volt swing to send a signal. USB communications use a 0.0 to 0.3 volt signal. With a larger amount of signal and the same amount of noise, RS232 has a much better signal to noise ratio than USB in the same environment.

What chipset does this adapter use?

  • It uses an FTDI USB to RS232 converter chipset.

Where can I download the latest driver version for this adapter?

    You can download the driver as a self installing executable

    This device does not have USB 3.0 capabilities.

    TunerStudio does not support IOS. For a display app, you could use RealDash, which would connect over WiFi with a suitable WiFi to RS232 adapter.

    It should work if it has a FTDI chipset, and will probably work if it has a Prolific chipset. Some other chipsets like the CH340 are more problematic. We would not be able to provide technical support for diagnosing problems that appear to be caused by the Insignia adapter if any arise; you would need to contact Insignia's technical support if you run into driver issues or similar problems.

    Yes. We use them for this combination all the time at our shop.

    Please try downloading and running the latest Windows driver, and see if that fixes it. We are using these on Windows 10 computers at our shop without any trouble.
